PATENT OFFICE.

WILLIAM S. SAMPSON, OF BROOKLYN, NEW YORK.

OAR-COUPLING.

I SPECIFICATION forming part of Letters Application filed June 6, 1881.

To all whom at may concern:

Be it known that I, WM. S'SAMPSON, of

. the city of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Automatic Couplers for Cars, (being especially an improvement on the car-coupler patented by me October 5, 1880, and numbered 233,028,) of which the following is a specification.

My invention relates solely to that class of railroad-car couplers which can be operated, by means of levers, from the top of the caror from either side of the car, enabling the brake- 'man in either position to perform the act of coupling without entering between the cars from the ground or descending from the roof.

The purpose of my improvement is to simplit'y the construction of this class of coupler,

and thereby reduce the cost of make, and incidental to this the cost of repairs; also, to lengthen the two vertical bars, that the grasping end of both may be brought nearer the bottom of the car and the leverage for the movement of the horizontalbar be in proportion increased. I accomplish these ends by the mechanism illustrated in the accompanying drawing, showing a perspective view of the end of a common box-car, wherein- A is the lever to be manipulated from the roof of the car, and its extension at B serving as a hold for operating the coupler on one side of the car, and the lever G for operating the same on the opposite side of the car. The fulcrum of the two levers is seen at a b, and the levers themselves are each attached to the horizontal bar D by movable joints d c. This bar D carries a projection or lip, E, upon its upper edge, near the center, which lip impinges against the. outer face of a double camshaped abutment, F. The coupling-hook for engaging with the draw-bar of another car is seen at G. Two guides for the horizontal bar D are seen at H H. Two small friction-pulleys, having V-shaped rims for guiding the chain L, are seen at K K.

The operation of this mechanism is as follows: If seated upon the roof of the car, grasp the ,vertical lever at A and draw it toward you Patent No. 245,021, dated August 2, 1881.

(No model.)

Q a short distance, (see dotted line,) or thrustit from you a short distance. The result to the coupling-hook is the same. This throwing of the lever out of the vertical moves the horizontal bar D, drawing with it the attached chain L over :one or the other of the pulleys K, and as a consequence elevates the outer end of book G to the position shown in dotted lines, in which position it will remain until the hand, by grasping either of the levers, moves the bar D back again to the central or coupling position shown in the drawing. When the operator is upon the ground at either side of the car he may grasp either lever nearest him at B or G and move the bar D, the same as if operatin g the long lever A upon the root. In the movement of the bar D the lip E, in

passing over either corrugation, springs the bar outward sufficiently to create all the friction necessary to hold the hook G inits elevated position.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is-- 1. In a car-coupler, the double cam-shaped abutment F, with its outer edge undulating in shape, as and for the purpose herein described.

2. In a car-coupler, the vertical lip E, attached to the horizontal bar D, in combination with the double cam-shaped abutment F, for the purpose herein set forth.

3. In combination with each other, the lever A, the horizontal bar D, with vertical lip E, the double cam-shaped abutment F, and coupling-hook G, as and for the purpose herein set forth and described.

4. In a car-coupler, the switch-lever A and the auxiliary lever O, in. combination with horizontal bar D, vertical lip E, double camshaped abutment F, pulleys K K, chain L, and coupling-hook Gr, all substantially as described.
